Aaplication filed December 20, 1913. Serial No. 807,317.2?5.A

.5 county ok'fCool, State of Illinois, ,have inventedffcertain new and useful Improvementslindiyeglasses. of which the follfm-'ing -isfa specification. lhlsjinvention relate to attaching means @for-"non-metalilic brides,` temples or other laccessories of eyeglasses and' spectacles, and hasifor' its-object to proiidb a simple and :effective structural formation and combina- .tionpf parts -wherebyea strong and econom- 1`5-. icalfconneetion between theclips .of rimless flens'esand the bridges and other accessories of eyeglasses and spectaclesA is effected,l

ande` Withiwhich, in addition, a veryelose arrangement of the axes of the'lenses, with ample span of the connecting bridge is at tained. I Y l A further object is to pxbvid in con ectioir with the above mentioned interme iate,

attachment, means for the support/*of fingeri piece mountings of eyeglasses and the operating springs therefor, all as will hereinafter more fully appear.

Inthe accompanylng draivings: Figure 1,

is a top view illustrating the present invention as applied to finger piece Y rimless eyeglasses. Fig. 9., is a front elevation of the same. Fig. 3, is an enlarged detail plan view of the clip and bridge olf the same. Fig. 4, is an enlarged detail sectional eleva- Fig. 5, is a detail side View of the clip, illustratlng the formation thereon of the hollow post for the iinger piece lever and operating spring. Fig. 6, is a like View of another type of the same.

40 Fig. 7, is a detail plan view of a modified 'form of the present invention.

Similar reference numerals indicate like parts in the several views.

Referring to the drawings, 1 represents the lenses of a pair of eyeglasses or spectacles of the rimless type, andfwhich are connected together by a connecting bridge 2, which in the present improvement consists .of-a transparent or semi-transparent material which is ductile and capable of being worked into shape nder a moderate degree of high temperature, such material for eX- ample being glass or Celluloid. Connecting bridges, etc., of the above described materials are necessarily circular or oval in vcrosssection, in order, to attain thev maXi-.

volves the following simple a'ndfe'conomical Y construction whereby such specific form of bridges, etc., are connected in a substantial v lmanne-r to the lenses of eyeglasses and spee- -taclcs v 3 is a clip member of any/ ordinary con- A,struction and tixcdly attached 'in any usual manner to its lens member '1.` The form shown in the Aclrawiinef for `the salie of illustration, is of a box type, adaptedto be cemcited tothe rim of the' len's member aforesal 4, is a Vtubular'sockct member `fixedly connected to the clip member 3 vnear the middle of the same, \an`d in the,"p'referred form of the present invention said socket member projects` in an oblique and substantially horizontal direction from the clipmember 3, as. shown in Figs. l, 2 and 3. The purpose being to attain an extended length 'of theI socket member Without material increase in the distance between the optical centers of the lenses and without a reduction in the j span of the connecting bridge 2. The bore of said tubular socket member el. is preferably ofa uniform diameter, and is either of a circular or oval form in cross-section, so

as to receive the correspondingly formed' end of the connecting bridge 2,which in an assemblage of parts is fixedly connected or otherwise secured therein.

5 is a tubular post secured to the tubular socket member 4, in adjacent relation to the clip member 3. Said tubular post is formed with a screw-threaded bore for the reception of the shank portion of the headed screw 6 by W iich the lever and spring of the hereinaftr described finger piece mounting is supported in place. The construction being such that with the screw 6 in place its head portion will have bearing against the top of the tubular post 5, so that'suicient frictional contact may be attained at such point, to prevent accidental disengagement of the screw and the parts confined thereby during continued actual use. The tubular post 5 may be formed as a separate piece and brazed in place on theI socket member 4', as illustrated in Fig. 6, or it may constitute an integral part of said socket' member, as illustrated in Fig.

loe

i applying the eyeglasses to the nose, and in the removal of the eyeglasses after use.

vl0 is a-spring of any" usual form encompassing the tubular post 5, with one end in operative engagement with the lever 7, and

' the other end in abutment engagement with the clip 3, or other fixed part of the eyeglass, the construction being such as to provide a yielding stress upon the lever 7 to move the same in a direction which will cause the nose grip 8 to bear-'against thenose of the wearer.`

The construction shown in Fig. 7, is more especially adapted for spectacles, and affords a very close arrangement of the optical centers oi' the spectacle lenses and at the same time provides an ample span of the connecting bridge 2.

While my invention is more especially adapted for use in connection with transparent or semi-transparent non-metallic bridges, the scope of the present inventionl embraces, the application of my specific construction heretofore described to the attachment of spectacle temples of the material above described, to their pivot members.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

1. In an eyeglass, the combination of a pair of lenses, a connecting bridge of nonmetallic material and having a rounded cross-section, and a pair of lens clips engaging the lenses and having tubular socket extensions adapted to receive the ends of the bridge, the said tubular extensions being disposed in an oblique direction with relation to the plane of the aforesaid clips and lenses, substantially as set forth.

2. In an eyeglass, the combination of a pair of lenses, a connecting bridge of nonmetallic material and having a rounded f cross-section, a pair of lens clips engaging the lenses and having tubular socket extensions adapted to receive the ends of the bridge, and tubular posts mounted on said socket extensions and adapted to support the carrying levers and actuating springs of a pair of nose grips, substantially as set forth.
